New
Grimson et al., Ithaca, United States. In J Cell Sci, 15 Jul 2015
RNA sequencing indicates upregulation of Atm in spermatocytes from miRNA-deficient mice, and immunofluorescence imaging demonstrates an increased abundance of activated ATM kinase and mislocalization of phosphorylated MDC1, an ATM phosphorylation substrate.
DNA damage primes the type I interferon system via the cytosolic DNA sensor STING to promote anti-microbial innate immunity.
New
Impact
Gekara et al., Umeå, Sweden. In Immunity, Mar 2015
Dysfunction in Ataxia-telangiectasia mutated (ATM), a central component of the DNA repair machinery, results in Ataxia Telangiectasia (AT), a cancer-prone disease with a variety of inflammatory manifestations.
Anthracyclines induce DNA damage response-mediated protection against severe sepsis.
Impact
Moita et al., Lisbon, Portugal. In Immunity, 2013
This salutary effect is strictly dependent on the activation of DNA damage response and autophagy pathways in the lung, as demonstrated by deletion of the ataxia telangiectasia mutated (Atm) or the autophagy-related protein 7 (Atg7) specifically in this organ.
Expression pattern of ataxia telangiectasia mutated (ATM), p53, Akt, and glycogen synthase kinase-3β in the striatum of rats treated with 3-nitropropionic acid.
GeneRIF
Pelegrí et al., Barcelona, Spain. In J Neurosci Res, 2012
We examined whether cellular expression of ataxia telangiectasia mutated, p53, Akt, and glycogen synthase kinase-3beta, were involved in the striatal neurodegeneration in the brains of rats
Pathological neoangiogenesis depends on oxidative stress regulation by ATM.
Impact
Kubota et al., Tokyo, Japan. In Nat Med, 2012
The ataxia telangiectasia mutated (ATM) kinase, a master regulator of the DNA damage response (DDR), acts as a barrier to cellular senescence and tumorigenesis.
Wip1-dependent regulation of autophagy, obesity, and atherosclerosis.
Impact
Bulavin et al., Singapore, Singapore. In Cell Metab, 2012
Here, we show that Wip1 phosphatase, a known negative regulator of Atm-dependent signaling, plays a major role in controlling fat accumulation and atherosclerosis in mice; specifically, Wip1 deficiency prevents both conditions.

Impact
Herrup et al., United States. In Nat Med, 2012
Here we report that ataxia telangiectasia mutated (ATM) deficiency causes nuclear accumulation of histone deacetylase 4 (HDAC4) in neurons and promotes neurodegeneration.
Cytoplasmic ATM protein kinase: an emerging therapeutic target for diabetes, cancer and neuronal degeneration.
Review
Burn et al., Sioux Falls, United States. In Drug Discov Today, 2011
The gene mutated in this disease, Atm (A-T mutated), encodes a serine/threonine protein kinase that has been traditionally considered to be a nuclear protein controlling cell-cycle progression.
Common variants near ATM are associated with glycemic response to metformin in type 2 diabetes.
Impact
GeneRIF
Pearson et al., Dundee, United Kingdom. In Nat Genet, 2011
ATM, a gene known to be involved in DNA repair and cell cycle control, plays a role in the effect of metformin upstream of AMP-activated protein kinase, and variation in this gene alters glycemic response to metformin
Mdm2 links genotoxic stress and metabolism to p53.
Review
Li et al., Shanghai, China. In Protein Cell, 2010
Mdm2's oncogenic activity is mainly mediated by p53, which is activated by various stresses, especially genotoxic stress, via Atm (ataxia telangiectasia mutated) and Atr (Atm and Rad3-related).

Review
Li et al., Shanghai, China. In J Cell Biochem, 2010
